Speaking at a joint news conference with EU foreign policy chief Catherine Ashton in Sarajevo on October 30, Clinton voiced hope that Tehran would soon start "serious, good faith negotiations" over the issue.

Ashton, who is also the world powers' chief negotiator with Iran, said on October 30 that European officials met last weekend with aides to Iran's top nuclear negotiators, Saeed Jalili.

She said she plans to meet directly with Jalili soon. Several rounds of talks between world powers and Tehran have failed to produce much progress.

The West suspects Iran's nuclear program is aimed at developing nuclear weapons. Tehran denies the charge.
